An RF dryer for the processing of ceramic catalytic converter and diesel particulate filter (DPF) substrates that uniformly removes moisture, eliminates surface cracking, and saves drying time, energy, and floor space requirements has been introduced by Radio Frequency Co., Inc. of Millis, Massachusetts.

The Macrowave™ RF Drying System for thin- and standard wall thickness ceramic substrates operates at 40 MHz which removes moisture more uniformly than dryers at 27- or 13 MHz and microwave frequencies. Eliminating the surface cracking caused by stresses of uneven shrinkage in conventional drying, RF selectively dry only the wet areas.

300kW(3) Zone Dryer

Featuring instantaneous heating throughout the ceramic substrate, the Macrowave™ 40 MHz RF Drying System needs less dwell time than a conventional dryer, which saves floor space and energy. Operating at up to 60% lower voltage than 27- 13 MHz dryers, this 40 MHz dryer processes materials at very low moisture levels without the arcing problems associated with lower frequency dryers, claims the firm.

The Macrowave™ 40 MHz RF Drying System is priced from $300,000 up, depending on configuration. Literature is available upon request.
